They probably used the wrong type of plastic and/or didn't set it right. The guy that made up the blueprints for this tested a few (barrels switch out) and they did just fine. also this only shoots .380's so it's not like the pressures of a 9mm or .40.

If they were trying to prove they are unsafe to stop people from going out and doing it themselves wouldn't they just alter the data to show it being dangerous themselves...you don't see the flaw in all of this?! the police tested these to show the public they are unsafe to make and use, but our test over here following the schematics show they work just fine. It doesn't set off red flags to you that it's all in house testing that can be altered to fit the police officers needs....??
